Catch Me If You Can Verse by   afterthenovels

In the end, catching Kurt Hummel is definitely not what Blaine expected.

Special Agent Blaine Anderson catches con-man and art thief extraordinaire Kurt Hummel twice, and on the second time they strike a deal. They’re supposed to just solve white collar crimes together, but they might even end up solving each other in the process.

A White Collar AU.

The Heir by @klaineanummel

Kurt Hummel is not having a good week. He just got thrown out of his half-sister's wedding, his dad cut him off, and he's being forced to work a real job for the first time in his life. He's pretty sure that things can't possibly get any worse.

That is, of course, until his step-brother Finn (and the only family member he genuinely likes) is found dead at the base of the Hummel Enterprises building.

Although his death is originally ruled a suicide it is soon discovered that it was anything but. Soon, Kurt finds himself thrown headfirst into a dangerous murder investigation; one which somebody does not want him to get out of alive.

Kurt and Blaine are both special agents (their history is canon, but they are in the future, and married, maybe their history is canon until s5 ending)

They are work different agency, and they don’t know that the other is an agent. Kurt work at Vouge.com, but reality it’s a CIA buliding, and Isabelle is his agent boss, and his cover story is fashion show when he need to leave for his real work.

and Blaine are working for the FBI or NSA or something, and he has his own cover job (i don’t have an ide for this one right now)

and then one time the two agency have a joined mission and they chose Kurt and Blaine and that’s when they realised that the other is an agent too, and they not really happy that they din’t figure out sooner, and they are kind of competitive when they work together, in a my agency are better than yours kind of.
